Safari Books is now available on a trial basis from the University of Iowa Libraries (trial period ends May 4 2012):

“In July, 2001, two of the world’s most prominent technology publishers, O’Reilly Media, Inc. and The Pearson Technology Group, joined forces to create Safari Books Online. The premise was simple: compile the best technology books from the leading authors and publishers into an on-demand digital library that technology, digital media and creative professionals could quickly and easily search for reliable, definitive answers to mission-critical questions.”
